Determine if two vectors are parallel in Max Script

I am posting this here so I never have to look up how to do this.
The simple compact answer to determining if two vectors are parallel.
In Max Script.

First Example: Using Dot Product.

        V1  = [1,1,1]; ----------Vector #1
        V2  = [-1,-1,-1]; -------Vector #2
        nV1 = normalize(V1); ----Normalized Vector #1.
        nV2 = normalize(V2); ----Normalized Vector #2.
        dir = dot nV1 nV2; ------Dot product of normalized vectors.
        print("dot ==" + dir as string);

        --Negative 1 = Anti-Parallel.
        --ZERO       = Perpendicular/Orthagonal
        --Positive 1 = Parallel.

        --Does anyone know if there is a word for "Non-Integer" besides "Float"?

Another way:
This uses Cross Product to determine if two vectors are parallel.

        V1  = [1,2,3]; ----------Vector #1
        V2  = [-1,-2,-3]; -------Vector #2
        dir = cross V1 V2 -------Cross of both.
        print("cross==" + dir as string);

        --If cross==[0,0,0] then you have 
        --parallel or anti-parallel vectors
        --or one or more vectors has a length of zero
        --Only vector with length of zero: [0,0,0];
